Thanks for the reply. What does it use as an advance now? and i took it to the shop yesterday to get the timming checked, and they turned the idle down WAY to low. I think they just wanted a reason to get my money "it should help your gas mileage" Does that make sense? Lower idle = more mpg?

Anyways, i'll definatly take your advice. Just tell me how. I recently replaced all the vacuum lines(all were put in original places, and the problem started before this)
